Answer: 12 inches
Step-by-step explanation:
We know that the volume of a rectangular prism is given by :-
Given : A toy chest in the shape of a rectangular prism has a volume of 8,640 cubic inches.
The base area of the toy chest is 720 square inches.
Let h be the height of the toy chest, then we have
Hence, the height of the toy chest = 12 inches

namely, let's rationalize the denominator in the fraction, for which case we'll be using the <u>conjugate</u> of that denominator, so we'll multiply top and bottom by its <u>conjugate</u>.
so the denominator is 5 + i, simply enough, its conjugate is just 5 - i, recall that same/same = 1, thus (5-i)/(5-i) = 1, and any expression multiplied by 1 is just itself, so we're not really changing the fraction per se.
Answer:
<em>95% of confidence interval for the Population</em>
<em>( 6.1386 , 6.8614)</em>
Step-by-step explanation:
<u><em>Step( i ):-</em></u>
<em>Given random sample size 'n' =85</em>
<em>Mean of the sample size x⁻ = 6.5 years</em>
<em>Standard deviation of Population = 1.7 years</em>
<em>Level of significance = 0.95 or 0.05</em>
<u><em>Step(ii):-</em></u>
<em>95% of confidence interval for the Population is determined by</em>
<em></em><em></em>
<em></em><em></em>
<em>( 6.5 - 0.3614 , 6.5 + 0.3614 )</em>
<em>( 6.1386 , 6.8614)</em>
<u><em>Conclusion</em></u><em>:-</em>
<em>95% of confidence interval for the Population</em>
<em>( 6.1386 , 6.8614)</em>
